help me with my set-up..

[yangtech]

hey,

this is what i have so far... n1 dp, n1 catback, 2.5" o2 housing, GM MAFT, intake, 255 pump..

i'm about to order the UICP for my stock ic and was wondering if i should stick with my 1g bov and vent it to the air or go aftermarket bov... i dont really want to spend the money on a aftermarket bov if i dont have to. i'm planning to run 20+ psi after it's all said and done with bigger injectors, big 16g or 50 trim t3/t4 and FMIC.

i'm also debating if i should get in SBR manifold and aftermarket intake manifold or get an FMIC first...

any suggestion or comment will help...

you answered your own ??? if you don't wanna get a aftermarket bov then don't. i would deffinatly get a fmic. i have seen the stock bov into the 10's but that was also crushed. there is another option, crushing the stock bov. but with 20psi i think a crushed stock bov should be fine. if you wanna be "fast and furious" then get a aftermarket bov. i know of some people just buy the after market bov just too have a different sound. then they blow it offf all the time

thanx for answering the bov question, that's what i wanted to hear...

 

[tpr103]

witha 16g or b16g you do not need a fmic right away but if you go with a 50 trim you should have it. i would upgrade the support mods first ex: boost control, fuel pump, injectors, exhaust, intercooler, then turbo!!! i know you already have most of the upgrades so your well on your way. remember mod once mod right.

Don't vent your BOV and an aftermarket Intake Manifold should be one of your VERY LAST mods.

He is going with a maft. Vent your stocker, it will hold, if it leaks you can always crush it. FMIC is a nice upgrade, and yes the intake manifold should be a later mod. Don't forget injectors with a bigger turbo, you also may need an safc to tune with or a logger.

 

[yangtech]

thanx guys, i'm trying to mod it right the first time so that i wont have to waste money on things that i dont want or need... i'm leaving the intake manifold last so what about the exhaust manifold...

 

[Quasimondo]

Either a 2G manifold or an Evo III manifold will work fine. If I'm not mistaken, if you go with teh EvoIII manifold you will have to open up the exhaust housing inlet to 7cm.

 

[yangtech]

i was thinking about getting some 680cc injectors as my next mod before the intercooler... would this be a good idea..?

 

[xerikx]

I think the best idea for you if you haven't done this already is to purchase some logging equipment next, (dsmlink, logger/shareware) something that will help you keep tabs on your setup so far. Then after that you can get into some injectors and an AFC (if that is the route you choose) and what not. Make sure too before you get too ahead of yourself that everything else is in proper running order also so nothing goes sour on you like I've seen many times. Best of luck.

 

[oldman]

Your next mod should be an AFPR for the 255. Slow down and do it right.

 

[oldman]

He is going with a maft. Vent your stocker

Just want to add that you can still recirculate to help keep the turbo spooled between shifts. If you got the GM maft so you can vent then vent. If you got it for performance reasons, I would try it both ways and then make a decision.

i want to get some data logger but if i do it, would i still need to buy a wideband 02 sensor..?

 

[xerikx]

no, a wideband 02 is not needed right away for logging. I use a palm 105 and shareware and even tho it will lock up once in a while it still gets the job done for now. Take to heart what Oldman said. Do some research on logging and make the best desicion you can and get one, hook it up and make sure your car is in running order. Then head off to injectors,afc, and fpr and have fun. By then you will prolly need a new clutch......

What are your plans for the car? Daily driven? track only? a little of both? are you stuck with 91 oct in WI?

 

[yangtech]

i did a bit of searching on data logging and i'm probably going to order one next week... i have another car as a daily driver so this car is mainly for track and weekends, for fun. We got 93 oct. up here in wisconsin...

Check out the Scanmaster from www.fullthrottlespeed.com for logging and even better it also allows you to see the action as it is happening like your 02voltage and knock sum. You can change to one of around 15 different pieces of operating data including timing advance. It comes with MMcd software and a cable for use with a palm if you wish to record. I don't bother, just tune as I drive. Mark

the link didn't work for me...


also i have been looking around at some intercoolers and was wondering if anyone knows of any other place that sells intercoolers for a good price. dont need a race kit, just street intercooler kit.

 

[sweet97]

www.fullthrottlespeed.com

www.dejontool.com has a street front mount hat will handle up to an EVO 16G without cutting the bumper.

It has been posted before that when you VTA on a 1g BOV at idle/under vac the BOV is sucking in unfiltered air. Sit down and really think about your goals and where you want to go. Get your fuel managment out of the way first, it will be your biggest pain in the ass.

 

[sweet97]

I use a MAF in a blow thru and VTA but never gave the unfiltered air intake a thought except that it was very minute. Not into it for the sound so perhaps I will mod my intake pipe to recirculate. Check the ECU on the '91 to see if it is an EPROM unit. The maft is at best a stretch to regulate 650cc inj's. Timing can get quite high. I agree get the fueldone first. Pump, AFPR,gauge and an EPROM chip from dsmchips perhaps if you can. Mark

 

[yangtech]

i'll do that and get the fuel mods first, but would it be ok to get the 680's or would i have to pretty much stay with the 650's, cause of the timing issue..?

in the mean time what about this intercooler..? http://www.diamondstarmotorsport.com/fmicparts.shtml

thanx..

 

[sweet97]

680's shold be OK. Have you deceided upon what turbo you will be getting? Makes a big differencein IC choice. Then you will need an AFPR-adjustable fuel pump regulator. I use the one from fulltrottlespeed which cost me $145. Then you would be able to lower the fuel pressure which may help with the MAF-T adjustment an timing issue. Mark
PS: Bigger turbo requires more IC. Are you willing to cut the bumper?
The EVO 16G is quite a turbo and can get you to the 325whp level fairly easily. I had the EVO,then 50trimand now a 60-1. Would have been just as happy with the EVO and quite a bit more in the bank!

 

[yangtech]

did more research and i'll be happy with the 650 injector and afpr.

i have thought about the b16g but it's just not big enough for me, i'm really hoping to get the 50 trim or a little bigger...

 

[sweet97]

Well www.agpturbo.com. RS49T/50trim or RS60T/60-1. Take your pick, $699. plus $100. for oil lines and another $100. for an internalwastegate.

 

[gixrman]

Water injection. You can run a normal size intercooler and not worry about hugh pressure drop.

You can run 680's, what type of fuel managment do you plan on running?
